[PDF]Get PriceOrganic phosphorus fertilizers come primarily from mineral sources, like rock dust or colloidal phosphate (also called "soft phosphate"), or from bone sources, such as steamed bone meal or fish bone meal. Mineral phosphorus sources are cheaper and last longer in the soil. Bone sources are more readily absorbed by plants.
